Product Overview
The Emerson KL3105X1-BA1 is a Thermocouple/mV Characterization Module (CHARM) designed specifically for DeltaV™ Electronic Marshalling systems. It serves as a high-performance input module capable of accepting thermocouple and millivolt signals with high precision and accuracy. This CHARM module enhances the flexibility of control systems by allowing users to easily configure and reconfigure I/O without field rewiring.
Its integration into DeltaV™ systems enables seamless control and monitoring of temperature and low-voltage signal inputs from field instruments. The KL3105X1-BA1 supports multiple thermocouple types, ensuring adaptability across a wide range of industrial processes.
This module is ideally suited for industries requiring precise temperature monitoring and control, including oil & gas, power generation, petrochemical, pharmaceutical, and food processing sectors.
